June was pretty busy for the crew of Expedition 56. With all of the maintenance and experiments performed by the six-person crew, you'd think they were busy enough! But no, they also had to prepare for a spacewalk and to make preparations for a new Dragon Cargo ship. On June 14, astronauts Drew Feustel (Expedition 56 commander) and Ricky Arnold (flight engineer) performed a6 hour 49 minute EVA to install improved HD camera equipment on the outside of the station.

The two spacewalkers  installed the HD cameras to help improve the view of the upcoming Dragon crewed ship docking and future Boeing Starliner crew vehicle dockings. In addition to the cameras, they moved some grab handles and performed some maintenance outside the Japanese KIBO module.

Following liftoff on Friday, and a three-day orbital chase, another Dragon cargo ship arrived at the ISS and was captured by robotic arm on Monday July 2. Astronauts Ricky Arnold, backed up by Drew Feustel, maneuvered the craft to dock at the US-built Harmony module. It carried science equipment, supplies, and biological experiments. Dragon is scheduled to stay at the station for about a month.
Parking is getting pretty limited up there.
 
With the arrival of Dragon, the ISS ports look pretty full. There are two Soyuz crew vehicles, a Cygnus cargo ship, a Dragon cargo ship, a Russian Progress cargo ship, and the inflatable Bigelow BEAM module attached to docking ports. Soon, however, we can expect further US-built crew ships (Dragon2 and Boeing Starliner) to be arriving for testing. This will make parking very interesting at the ISS!

Spring has gotten off to a good start up in Low Earth Orbit. When the Expedition 54 crew left the station on March XX, it left only three crew aboard: Expedition 55 Commander Anton Shkaplerov (Roscosmos) Norishige Kanai (Japan) and Scott Tingle (NASA). They did not have long to wait. On March 23, the reinforcements arrived on Soyuz spacecraft MS-08, docking at the Russian-built Poisk module. Joining the crew was Soyuz commander Oleg Artemyev (Roscosmos), Dr. Andrew Feustet (NASA), and Rick Arnold (NASA). Comprising the Expedition 55/56 crew, they are all veterans of spaceflight with Artemyev having already visited the ISS for six months in 2014. Dr. Feustel flew aboard shuttle Atlantis in 20009 with the Hubble Servicing Mission, shuttle Endeavor's final mission in 2011 (STS-134), and already has six EVAs to his credit. He will The Expedition 56 commander at the end of Expedition 55. Astronaut Arnold flew aboard shuttle Discovery in 2009, delivering the last set of solar panels to the ISS.

 The last week of March was a busy one for the full crew. On March 28, ISS crewmembers closed the hatch on Progress 68P, having removed all its cargo and replaced the cargo with trash and waste items. The Progress ship undocked from the Russian-built Pirs module and was maneuvered into a lower orbit. Russian ground controllers are using the craft for some engineering tests, until they are ready to de-orbit the craft on April 25 and let it burn up over the Pacific Ocean.

The next day, March 29, two of NASA's astronauts went outside for a spacewalk, the fourth of the year. Astronauts Feustel and Arnold performed an EVA for a little over six hours, replacing worrisome cables on a cooling system, installing a TV camera, and placing a new communications antenna on the US Tranquility module.

With the spacewalk completed, astronauts began preparing for their next visitor. On April 2, SpaceX launched another resupply mission to the ISS using the Falcon 9 re-usable rocket and the Dragon cargo spacecraft. Mission CRS-14 brings the station a plethora of science equipment as well as consumables and regular maintenance items. Dragon reached the station and docked on April 4 to the US Harmony module. It will remain on the station until May.

The Soyuz capsule landed on the cold wintery steppes of Kazakhstan early on Tuesday. They were quickly joined by recovery crews flying in by helicopter and were carefully retrieved from the cramped descent module. For Soyuz commander Alexander Misurkin, he now has his second spaceflight complete. He took part in a record-breaking Russian EVA on February 2, and now has a total of 4 spacewalks in his resumé. Astronaut Joe Acaba has now completed three spaceflights, with three EVAs total. Astronaut Mark Vende Hei has completed his first space mission, and now has a fantastic four EVAs to his credit.

SpaceX Heavy Falcon Launches Tesla Roadster out to the Asteroids

The SpaceX Heavy Falcon sits on the pad the night before First Flight. All images credit: SpaceX.

In a bold, and risky test flight, SpaceX has created the world's currently-heaviest payload lifting rocket. The Heavy Falcon is basically a center prime stage with two attached Falcon-9 recoverable boosters to the sides. A second stage and payload sit atop the prime stage, which is also designed to land and be re-used. Until Wednesday, the rocket with the most lift was the Delta 4 rocket. The Falcon Heavy can lift a payload of 140,000 pounds to low Earth obit, 58,000 ponds to Earth Geosynchronous Transfer Orbit, and if needed, can launch over 37,000 pounds to Mars.  Only the giant Saturn V and perhaps the Russian Energia, both retired, could lift more.

Blast off on Wednesday afternoon after high winds abated.

The Falcon Heavy lifted off from the venerable Pad LC-39A at the Kennedy Space Center. This site was heavily used for most of the Apollo moon launches, followed by Skylab and then Space Shuttle launches. A few years ago, the Space Center signed a 20-year lease with SpaceX. The older tower support structures were removed, and SpaceX built a new tower system with rocket assembly and testing features around the pad. 

The Falcon-9 boosters landed perfectly back at the cape, at almost the same time.

Prior to the launch, Space X executives were keen to remind everyone that this as an extremely dangerous test, and it could fail. But alomst everything went right. As planned, the boosters separated and were remotely-guided down to land vertically at launch pads LZ-1 and LZ-2. These pads were built by SpaceX at the US Air Force's Cape Canaveral range just a little south of the Kennedy Space center. The site was originally Launch Complex 13, which supported testing and launches of the Atlas and Atlas-Agena rockets. Science missions Lunar Orbiter-1 and Mariner 3 were launched from there, as well as several spy satellites. Unfortunately, the prime center stage did not land successfully and crashed into the Atlantic Ocean.

The StarMan, in its SpaceX designed spacesuit, leaves Earth Orbit on its way to the Asteroid belt.

To confirm the test launch heavy lift capability, SpaceX needed a heavy object to launch into space. In a creative publicity move, SpaceX President Elon Musk donated a car from his personal collection - a Tesla Roadster with the convertible top down. Inside was "Starman" a dummy placed in a SpaceX spacesuit. Cameras on board the car recorded and transmitted images in different directions as the car left the orbit and continued its way out to space- estimated to be an orbit near the asteroid belt. In a tribute to some science fiction icons, a Screen in the car displays "Don't Panic" and the Starman has his space-traveling towel. A miniature Tesla car hangs from the front mirror. And the radio is broadcasting David Bowie's hit "Space Oddity" as long as power holds out.

Dragon Undocks and EVAs mark the beginning of 2018 on ISS.

Full of returning experiments, science samples, and items for further testing, the Dragon cargo spaceship undocked from the ISS on January 13. Surviving the fiery re-entry, the craft parachuted down to the Pacific Ocean and was recovered by SpaceX teams which will prepare the ship for returning to SpaceX and to NASA.
 
 
 Astronaut Scott Tingle prepares for the year's first EVA.
 
January and February start off with EVAs on the International Space Station. On January 23, astronauts Mark Vande-Hei and Scott Tingle conducted EVA-47 to replace parts on the Robotic Arm. Once outside the airlock, the spacewalkers removed the spare part from a locker on the outside of the station and replaced the faulty part on the arm. Unfortunately there is a software issue with the activation of the part, which will result in a further spacewalk later in February.
 
Russian Cosmonauts Alexander Misurkin (R) and Anton Shkaplerov (L) prepare to exit the airlock for their EVA.

February 2nd saw the second EVA when cosmonauts Anton Shkaplerov and Alexander Misurka exited the PIRS module to perform maintenance work. This was Misurkin's fourth spacewalk. They successfully moved to the Zvesda module and replaced a faulty electronics box for a high-gain radio communications system. The bad parts were jettisoned towards a burn-up in the atmosphere. This station marked the 207th EVA for maintenance on the spacestation, including both American and Russian spacewalks. Typical for space agencies, this is also known as the Russian EVA-44 spacewalk. I'm not sure that I can comprehend how they keep track of these things when they have duplicate designations...

The EVA concluded after 8 hours and 13 minutes, which makes it the longest Russian spacewalk. Coming up on the ISS: A Russian Progress Cargo ship will take off on Sunday Feb. 11, and another US EVA in this coming week.

Christmas visitors at ISS

Soyuz FG rocket lifts off the pad at Baikonur into a wintery blue sky.
 
On Sunday Dec 17, the second half of the Expedition 54 team left Russia for a two-day chase to the International Space Station. On board the Soyuz MS-07 spacecraft were Soyuz Commander Anton Shkaplerov (Roscosmos), Scott Tingle (NASA), and Norishige Kanai (JAXA). They docked at the station on Tuesday morning. 
Before the launch, at the simulator (L-R): Kanai, Shkaplerov, and Tingle.
 
This is Shkaplerov's third trip to the ISS. This time he will take over as station commander when the current lead crew returns to Earth. FOr Kanai, though this may be his first spaceflight, he previously made a two-week stay in the seabase off the Florida coast in 2015, simulating communications protocols in a future Mars mission with long signal delays.  Scott Tingle has been a Navy test pilot and also flew as a member of the elite Blue Diamonds demonstration team. He has 54 combat missions to his credit, and joined NASA in 2009. This is his first flight to space. 
Current spacecraft docking locations at the ISS.
 
November and December have seen a busy schedule of flights to and from the station. The Cygnus resupplu spacecraft arrived on November 13 for a three week stay. After delivering its supplies, the spacecraft undocked on December 6 for a 12 day period of free-flight testing, before entering the Earth's atmosphere on December 18 for a fiery end. During that time it also launched 14 Nanorack Cubesats.

On Thursday Dec. 14, Soyuz MS-05 undocked from the ISS for a return to Earth. In Command of the spacecraft was Sergei Ryazansky (Roscosmos), accompanied by Randy Bresnik (NASA) and Paolo Nespoli (ESA). Bresnik had been Commander of Expedition 53 before leaving the station in the capable hands of Misurkin, commanding Expedition 54.

Sadly, it has been reported that astronaut Bruce McCandless II has died. He was made famous around the world for the image of him in the shuttle EVA suit flying tether-free around the space shuttle. Most people are unaware, but he served as Houston Mission Control communicator during the historic moonwalk of Neil Armstrong and Buzz Aldrin on Apollo 11 in 1969. He also was part of the crew that launched the Hubble Space Telescope on STS-31 in the shuttle Discovery.
